According to Sina Finance News, on December 20, Liu Weiguang, vice president of Alibaba and president of Alibaba Cloud's new financial business department, said that Ant Financial has gone through 15 years, and every business progress is driven by technology. It is the "nuclear weapon" of Ant Financial. Ant Financial has been committed to using technology to solve the problem of trust between people, and blockchain is also an important part of it. Now the hot cross-border remittances are only a very small part of blockchain applications. Blockchain stacking up with other new technologies in the future will change our financial infrastructure.
